6.2.2 Semiannual Inspection
Semiannual Inspection is to be performed only by a Certified Firetrace Distributor. Inspection should include a repetition of the monthly inspection as
well as verification of extinguisher unit weight. Extinguisher unit weight should be verified using the following steps:
1. Remove the cylinder from the installation as follows:
• Close the ball valve, by turning the ball valve lever clockwise to the “OFF” position
• Depressurize, then disconnect the detection tubing at the ball valve.
• Disconnect the discharge network from the cylinder valve discharge ports(s)
• Immediately install the safety plugs(s) into the valve discharge port(s)
• Remove the cylinder from the bracket
2. Weigh the cylinder. Compare the measured weight with the weight found on the cylinder nameplate. If the container shows a loss
in agent quantity of more than 5 percent or a loss in pressure (adjusted for temperature) of more than 10 percent, the cylinder shall
be refilled or replaced.
3. Remove the nozzle(s) and inspect for obstructions. Reinstall the nozzles.
4. Reinstall the cylinder and discharge network, connect and re-pressurize the detection tubing with nitrogen following the applicable
procedures outlined in Section 5.
6.2.3 Five Year Inspection
FK-5-1-12 cylinders continuously in service without discharging shall be given a complete external visual inspection in place, every 5 years or more
frequently if required.
Follow external visual inspection guidelines detailed in Section 7 of NFPA 2001 (2015 Edition)
6.2.4 Firetrace Detection Tubing Maintenance
Firetrace detection tubing maintenance is to be performed by an authorized Firetrace distributor. Maintenance should include a complete external
visual inspection of the tubing during every monthly inspection. The tubing shall show no signs of physical damage or degradation, including but not
limited to abrasion, distortion, cuts, dirt accumulation. For any deficiencies that are found, appropriate corrective actions shall be taken immediately.
In addition to a monthly visual inspection, a semi-annual inspection is to be performed to evaluate the tubing for damage and pliability. If any
concerns are noted, replacement of the Firetrace detection tubing would be recommended.
If all routine maintenance is followed and inspection of the tubing determines the tubing to be in good condition and does not show signs of damage
or degradation, the tubing can remain in service.
NOTE: If a fire situation is experienced, any sections of tubing that have ruptured or have been damaged during a fire must be replaced. Sections can be
replaced by splice connections.
6.3 Hydrostatic Testing
Firetrace FK-5-1-12 cylinders are built to DOT-4B specifications and therefore fall under DOT CFR Title 49 & NFPA 2001 regulations for retest and
inspection.
All DOT-4B, 4BA and 4BW cylinders used exclusively in FK-5-1-12 service are to be retested and reinspected per DOT CFR Title 49, Section 180.205
& 180.209 as well as NFPA 2001, Container Test Section at the prescribed intervals for the cylinder/agent type used. All retest/reinspection must be
performed by an authorized retester having a current identification number issued by the Associated Administrator for Hazardous Material Safety of
DOT and must follow the test procedures as described in the applicable CGA pamphlet.
A complete visual inspection can be used in lieu of hydrostatic testing if cylinders are undamaged following the guidelines in DOT CFR Title 49, Section
180.205 & 180.209 as well as NFPA 2001, Container Test Section. Subsequent inspections as described in DOT CFR Title 49, Section 180.205 &
180.209, NFPA 2001, Container Test Section, as well as the local regulating authority will be required. The visual inspection shall be conducted only
by competent persons and in conformance with the applicable CGA pamphlet. Inspections must be made only by persons holding a current RIN and
the results recorded and maintained in conformance with DOT CFR Title 49, Section 180.215 & NFPA 2001, Container Test Section. Where external
visual inspection indicates that the container has been damaged, additional strength tests shall be required in accordance with applicable transportation
regulations.
